1 Claim.

' low cost washing apparatus which can be easily .and quickly associatedwith a cloth printing machine to thoroughly clean the gray cloth afterpassage through the printing machine and prepare it for return to suchmachine.

Other objects, novel features and advantages of this invention willbecome apparent from the following specification and accompanyingdrawings, wherein:

Fig. 1 is a diagrammatic view illustrating the washing apparatusconnected up to the printing machine;

Fig. 2 is a vertical section through the washing apparatus, and

Fig. 3 is a section on the line 33 of Fig. 2, partially broken away.

In Fig. -1, [0 represents the impression cylinder of a cloth printingmachine while each printing roller is designated by H. The cloth to beprinted is designated l2 while the gray cloth is designated I 3. Thewashing apparatus of this invention is designated generally by l4 andthe gray cloth I3 is passed through the washing machine and then aroundthe drying apparatus l5 before it is returned to the printing machine.

The washing apparatus 14 comprises a tank having a vertical partition l6dividing it into two chambers l1 and i8 of which the chamber [8 isconsiderably larger than the chamber l1 and the partition terminates ashort distance below the top of the tank. A frame I9 extends above thetop edge of the tank and is provided with side plates 20. A roller 2| isjournalled in the frame l9 above the chamber l8 near one wall thereof.In the bottom of the chamber l8 are joumalled a plurality of rollers 22,22a, 22b and 22c and rollers 23, 24 and 25 are rotatably supported bythe frame l9 at a considerable distance above the top of the chamber Hi.The rollers 24 and 25 are equal in size and larger than the roller 23.Additional rollers 26 and 21 of the same size as the roller 23 arerotatably supported by the frame [9 above the chamber [1 and in thebottom of the chamber I! are provided a pair of rollers 28 and 28a. Aroller 29 is journalled above the chamber I! and is connected'to drivingmeans (not shown).

A chain 39 in combination with sprocket wheels on the rollers 29 and 25comprises means for driving, the roller 25 by the roller 29 and a chain3| co-operating with sprockets on the rollers 21 and 28 constitutesmeans for driving the roller 24 by the roller 25. Archer 32 is supportedby the tank l4 adjacent the roller 29 and the rollers 29 and 32 areequipped with intermeshing gears, by means of which the roller 32 isrotated in the opposite direction to'the direction of rotation of theroller 29. A pair of arms 33 are pivotally supported by the frame l9 anda roller 34 is joumalled in said arm directly above the roller 29 andthe arms 33 are provided with an adjustable weight 35 tending to pressthe roller 34 against the roller 29. Means comprising a crossbar 36rotatably supported by the frame l9 and provided with an actuatinghandle 31 are provided for eilecting movement of the roller 34 away fromthe roller 29.

A water inlet pipe 38 leads into the chamber l1 and a vertical outletpipe 39 leads from the chamber [8, the liquid level in the chamber l8being controlled by the height of the pipe 39. A pump 40 has its inletconnected to the lower portion of the chamber I8 and has its outletconnected to a header 4!. Three horizontal pipes 42 are connected inparallel with the header 4| and each pipe is provided with a pluralityof nozzles 43. The pipes 42 are arranged at the corners of a trianglewith two pipes at the same elevation and the third pipe at a higherelevation. The nozzles 43 of the two lower pipes are directed toward theupper pipe, while half the nozzles of the upper pipe are directed ateach of the remaining two pipes. The pump 40 withdraws water from thetank l8 and supplies it to the nozzles 43. Fresh water is supplied tothe chamber [1 through the pipe 38 and water from the chamber I1 flowsover the edge of the partition l6 into the chamber l1. The level ofwater in the chamber i8 is maintained constant through operation of theoverflow 39.

A soiled gray cloth C is introduced into the chamber I8 over the roller2| from which it I passes down through the chamber l8 and aroundreversely to the direction of travel of the my cloth and serves tospread the gray cloth which then passes between the squeegee rollers}!and 34 which co-operate to remove substantially all the moisturetherefrom after which the gray cloth is supplied to the dryer II. On twoof its passes the gray cloth is led between opposed sets of nozzles 43and is subjected to water under pressure thoroughly to clean it, thegray cloth previously having been soaked in the liquid in the container[8. In the chamber II, the gray cloth is thoroughly rinsed in clearwater.

In order not to multilate the fibres forming the gray cloth, and therebyimpairing its'liie, a large volume of washing water at relatively lowpressureisused. The pumpissodesigned that the water passing from thespray males is delivered to the gray cloth at a pressure not exceedingfifty pounds and a sufiicient number of nozzles are provided withsufiicien't. volume of water at this pressure projected against thecloth to efi'ect the desired washing. With this arrangement. the life ofthe standard gray cloth is unimpaired by continuous washing and the useof a washer such as herein. described is Justified from a nnancialviewpoint.
